The price of oil rose 1 percent to close above $103 a barrel Wednesday, driven by severe winter weather in the U.S. and supply concerns.
Benchmark U.S. crude for March delivery rose 88 cents to $103.31 a barrel in New York, after surging $2.13 on Tuesday. The more heavily traded April contract was up 74 cents at $102.84 a barrel.
The last time the price of oil was above $103 was in October.

Meanwhile, expectations for an increase in oil supplies were dampened after Iran rejected a key demand of six world powers in their latest round of talks in Vienna aiming to finalize a deal to control Tehran's nuclear program. Iran, a major oil producer, will be able to export more crude if the talks lead to reduced sanctions.
Protests in Venezuela, one of the top five crude suppliers to the U.S., and snags in oil production in Libya and South Sudan also helped increase prices.
